This task takes one or more filenames and turns them into URLs, which it then assigns to a property. Useful when setting up RMI or JNLP codebases, for example. Nested filesets are supported; if present, these are turned into the URLs with the supplied separator between them (default: space).

Examples:

<makeurl file="${user.home}/.m2/repository" property="m2.repository.url"/>

Sets the property m2.repository.url to the file: URL of the local Maven2 repository.

<makeurl property="codebase"><fileset dir="lib includes="*.jar"/></makeurl>

Set the property codebase to the three URLs of the files provided as nested elements.

Attribute	Description	Type	Requirement
file	name of a file to be converted into a URL	File	optional, if a nested fileset or path is supplied
property	name of a property to set to the URL	String	required
separator	separator for the multi-URL option	String	optional
validate	validate that every named file exists	boolean	optional; default: true

fileset (org.apache.tools.ant.types.FileSet)

A fileset of JAR files to include in the URL list, each separated by the separator.

path (org.apache.tools.ant.types.Path)

Add a path to the URL. All elements in the path will be converted to individual URL entries.
